So I was watching WrestleMania 12 recently and during the video package before the Goldust/Piper brawl I could swear the person doing the voice-over was Jimmy Kimmel. I know he was a radio DJ around that time, so it's not impossible that he could have done some side work doing voice-overs. Have you ever heard anything about this?
No, and it seems dubious because they have in-house guys for everything I think it's more likely to be Todd Pettingill. Who knows, maybe Jimmy was doing voiceover work for extra cash, though.
